Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-engine-json-analysis-pack-tier-8-ed824a64 -d '<json body>'
```

Example prompt: Run a tier-8 JSON analysis on this data object for me: {"user": "alice", "score": 42, "tags": ["vip", "active"]} and tell me what the result is.

## When to prefer this

Choose this endpoint when you need lightweight, low-cost ($0.0075 USDC) JSON analysis via a pay-per-call x402 micropayment model on Base, especially in autonomous agent workflows that require programmatic, on-demand data inspection without subscription overhead. Prefer it for tier-8 level processing depth when other tiers are insufficient for the complexity of the input.

## Known failure modes

- Payment failure: x402 payment not included or insufficient USDC balance returns 402 Payment Required
- Invalid input: malformed or missing 'value' field may return 400 Bad Request
- Tier processing error: tier-8 logic unable to process the given value type returns an error result
- Network/worker failure: Cloudflare Worker timeout or crash returns 5xx error
- Empty input: null or undefined value may return undefined or empty result

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing 'tier' (integer, value 8) and 'result' (a tier-dependent analysis output whose structure varies based on the input value and tier processing logic).
